Convert BCM2835/6368 Random number generator bindings to DT schema.

Signed-off-by: Nícolas F. R. A. Prado <nfraprado@protonmail.com>

Changes in v2:
- Remove description for common properties
- Drop label from example

This patch was tested with:
make ARCH=arm dt_binding_check
make ARCH=arm DT_SCHEMA_FILES=Documentation/devicetree/bindings/rng/brcm,bcm2835.yaml dtbs_check

Thanks,
Nícolas

-Required properties:
-
-- compatible : should be one of
-	"brcm,bcm2835-rng"
-	"brcm,bcm-nsp-rng"
-	"brcm,bcm5301x-rng" or
-	"brcm,bcm6368-rng"
-- reg : Specifies base physical address and size of the registers.
-
-Optional properties:
-
-- clocks : phandle to clock-controller plus clock-specifier pair
-- clock-names : "ipsec" as a clock name
-
-Optional properties:
-
-- interrupts: specify the interrupt for the RNG block
-
-Example:
-
-rng {
-	compatible = "brcm,bcm2835-rng";
-	reg = <0x7e104000 0x10>;
-	interrupts = <2 29>;
